^Adam, F. & Innes of Learney, T. (1952). The Clans, Septs, and Regiments of the Scottish Highlands (4th ed.). Edinburgh & London: W. & A.K. Johnston Limited. p. 401 ("Scottish law and nobiliary practice, like those of many other European realms, recognise a number of special titles, some of which relate to chiefship and chieftaincy of families and groups as such, others being in respect of territorial lairdship. These form part of the Law of Name which falls under the jurisdiction of the Lord Lyon King of Arms, and are recognised by the Crown. [...] As regards these chiefly, clan, and territorial titles, by Scots law each proprietor of an estate is entitled to add the name of his property to his surname, and if he does this consistently, to treat the whole as a title or name, and under Statute 1673 cap. 47, to subscribe himself so").
